On January 3, 1959, Provine appeared as Laura Winfield in the episode "The Bitter Lesson" of the NBC western series Cimarron City. Laura Winfield is a newly arrived schoolteacher with false credentials who is plotting with a male companion to rob a stage shipment of gold, but not before Deputy Sheriff Lane Temple (series star John Smith) falls in love with her. Dan Blocker and Gregg Palmer also appear in this episode as interested suitors of the new teacher.[6] A few weeks thereafter, she was cast in a supporting role in the episode "The Giant Killer" of the ABC/Warner Bros. western series Sugarfoot, with Will Hutchins in the title role.

Provine had a starring role in two ABC/WB series: The Alaskans (1959–1960), in the role of Rocky Shaw and with Roger Moore, and The Roaring 20's (1960–1962), in which she played the beautiful singer Pinky Pinkham. A profile in Time stated that "It is Dorothy’s oooohing and shimmying that have kept the series afloat."[5] Rex Reason, from Man Without a Gun, co-starred with her in The Roaring 20s, along with Donald May, John Dehner, Mike Road, and Gary Vinson. Provine recorded an album of songs from the show, and had two hit singles in the UK Singles Chart — Don't Bring Lulu" (number 17 in 1961) and "Crazy Words, Crazy Tune" (number 45 in 1962).[9]

She guest starred in the 25th episode of The Gallant Men called "Tommy", which aired in March 1963. Her character name was Joyce Adams, a singer who entertained the troops.

In 1968, Provine married the film and television director Robert Day and retired from acting, apart from occasional guest roles on television. The couple moved to Bainbridge Island, Washington, about 1990, where they resided with their son. Provine was somewhat reclusive in retirement and indulged her love of reading and movies and occasionally drove around the island with her husband.[10]
